testStoreSimulatedPurchaseError (error code 42): Test Store simulated purchase error

• The SDK is configured with a Test Store key (test_), and the Test Store dialog's failure button was tapped (SimulatedStorePurchaseHandler.swift).
• On Android, the same button is labeled "Test failed purchase", and it sends the error to the purchase callback (SimulatedStoreBillingWrapper.kt).
• The SDK's description is "Purchase failure simulated successfully in Test Store". That is the success message for this error.

• Do not retry for the tester. They chose the failure.
• Show the same failure message you show for real purchase errors, to test it.
• Do not grant access. No purchase happened.

// Swift
do {
  let result = try await Purchases.shared.purchase(package: package)
} catch let error as ErrorCode where error == .testStoreSimulatedPurchaseError {
  // handle test store simulated purchase error
}

// Kotlin
if (error.code == PurchasesErrorCode.TestStoreSimulatedPurchaseError) { /* ... */ }

On RevenueDot: RevenueDot never sees this error: no receipt is posted for a failed Test Store purchase. A successful Test Store purchase posts a test_<ms>_<id> token to POST /v1/receipts, and the purchase is always stored as sandbox. See Test Store and how to test purchases without real money.
